vm::*foreign-stack-size*[Global Variable]

Size in words of the foreign stack allocated for a thread. The foreign stack is used by foreign code, and for the stack allocation of untagged lisp objects such as numbers. On the x86 port the foreign stack is shared with the control stack. The size may be initialised upon startup by the -foreign-stack-size command line argument.
